TOOL-HANDLE FASTENING.

SPECIFICATION forming part of Letters Patent N 0. 659,523, datd d td'b r 9, 1906.

Application filed April 12, 1900. Serial No. 12,602. (No model.)

To all whom it may concern:

Be it known that I, ZAOHRY T. FURBISH, a citizen of the United States, residing at Phila delphia, Pennsylvania,have invented certain Improvements in Means for Securing Handles to Tools, of which the following is a specification.

The object of my invention is to provide a simple and effective means for securing han- 1o dles to tools.

My invention is especially adapted for securing the handles of ratchet screw-drivers and drills to the body of the device.

In the accompanying drawings, Figure 1 is a side view of a ratchet screw-driver, illustrating my invention, the sleeve at the handle being in section. Fig. 2 is a longitudinal sectional view of Fig. l, and Fig. 3 is a detached perspective view showing the means for attaching the handle to the body of the tool.

A is the body of the tool, which in the present instance is in the form of a tube attached to the ratchet-carrier B. Within the 2 tube is the threaded stem 0, carrying at its end a chuck O.

D is ahandle. In the present instance this handle is of wood and has a reduced portion D. The handle is bored out to fit the tubu- 0 lar body A of the tool, and the portion D of the handle is slotted at d, so as to allow the sections formed between the slots to yield when the body portion is driven in place.

The body portion A is grooved at a, and in 5 the groove is placed a ring E, and in the reduced portion D of the handle is an internal annular groove 01. The ring E is of such a diameter that it will partly enter the groove Ct in the body A and also enter the internal 4o groove d in the handle. The ring is split, as shown, and is preferably made of spring metal.

In placing the ringin positionI expand it,so

that it will pass over the body portion A and spring into the groove a. Then when the handle is forced onto the body portion the sections of the reduced portion D will yield to allow the ring to pass and enter the internal.

groove (1, thus locking the handle and the body portion together.

A sleeve F is placed over the body portion, as well as over the reduced portion of the handie, and is preferably secured to the two ele ments by a screw f, Fig. 2. This flange pre vents the sections of the reduced portion D of the handle from yielding, and consequent ly firmly locks the body portion to the handle.

In order to prevent the body portion from turning in the handle, I secure in the end of the opening in the handle a tube G, notched at 9, so as to engage the notched end portion a of the body A. This tube G also acts to relieve the ring E of end strain, as the thrust is taken directly bythis tube.

\Vhile I have shown an almost complete ring, it will be understood that a segment of a ring may be used and that while I have shown the body portion tubular it may be solid and the stop G in the handle may also be solid Without departing from my invention, and in some instances the ring may be fixed to the body portion or formed thereon.

I claim as my invention- 1. The combination of a handle having a split portion, an internal annular groove in the split portion, a body portion, a projection on the body portion resting in the groove in the handle, and means for holding the split portion of the handle, substantially as described.

2. The combination of a handle having a split portion and an internal annular groove in the split portion of the handle, the body portion of a tool, a groove therein, a ring or segment resting in the groove in the body por- '8 5 tion and the groove in the handle, and means for holding the split portion of the handle, substantially as described.

3. The combination of a handle having a split portion and having an internal annular o groove in the split portion, a body portion having an annular groove therein, a ring resting in the two grooves, and a sleeve on the split portion of the handle, substantially as described.

4:. The combination of a handle having an opening therein, a notched piece within the opening, a body portion notched at the end to engage the notched piece of the handle, an annular groove in the body portion, an inter- I00 nal annular groove in the handle, and a ring die and on the body portion, thus preventing or a segment of a ring resting in the grooves, the split portion of the handle from yielding, substantially as described. substantially as described.
